Yep, Cygwin native using 4.3.4 as bootstrap compiler. > I haven't been able to bootstrap for a few weeks, but no one answered my > email for help (which probably got lost in the kernel-related fighting): rofl Linus is such a git!

Like I said, 4.3.4 (and occasionally I bootstrap HEAD with itself), but this is one of those areas where false positives/negatives come and go. > Any help is appreciated -- I really want to get cracking on testing 4.5. I read the code in ira-lives.c; it is very clearly not used uninitialised, so this is undoubtedly a bug in your bootstrap compiler. File a PR, reconfigure your tree using --disable-werror, and off you go. cheers, DaveK
